“…Any depletion of this reserve may lead to reduced vigor directly, by malnutrition, and, indirectly by increased energy required for foraging, this would make the fry more vulnerable to environmental or biotic stresses. Further, Nonylphenol in the spray formulation increased two-fold the uptake of aminocarb by Chlorella from 3.5 pglpg dry wt to 6.5 pglpg dry wt, with little (> 30%) desorption [23]. In the present study increased fenitrothion uptake was also observed with Dowanol.…”

The emtoxicity of six widely-used adjuvants-namely, Aerotex 3470, Atlox, Cyclosol 63, Dowanol, Nonylphenol and 585 fuel oil-were extensively investigated with respect to an algal and forest seed model system. The adjuvants differentially affected the chemical and biological fate of the pesticides. All but Dowanol (> 1000 pg/mL) had the potential to perturb the growth of Chlamydomonas reinhardtil Dang. and the tree seeds of Jack pine (Pinus banksiana Lamb.) andPaper birch (Betulapapyrqera Marsh). Aerotex, Cyclosol and Nonylphenol (> 5 pg/mL) were the most active adjuncts tested.

“…12 However, some carbamate pesticides can promote the growth of phytoplankton and seedlings of some vascular plants. Aminocarb promotes the growth of C. pyrenoidosa 13 and carbofuran promotes the growth of Oryza sativa, Gossypium hirsutum and Arachis hypogea seedlings. 14 The total chlorophyll contents of the untreated plants, I. aquatica, P. stratiotes and H. dubia increased with increasing test durations.…”

The purpose of this study was to assess the effects of carbamate insecticide on the growth of three aquatic plant species, Ipomoea aquatica, Pistia stratiotes and Hydrocharis dubia. These three aquatic plant species were treated with different concentrations of carbaryl and test durations. The fresh weight increase, the dry weight per fresh weight and the total chlorophyll content of the treated plants decreased with increasing concentrations of carbaryl and the test durations. The leaf injury indices of the treated plants increased with increasing concentrations of carbaryl and the test durations, while the leaf injury indices of the controls were zero. The 96-hour EC 50 values of total chlorophyll content of I. aquatica, P. stratiotes and H. dubia were 0.996, 0.785 and 0.334 g/l, respectively. Moreover, chlorosis and necrosis occurred at the leaf margin of the treated plants, then they extended into the inner portion of the leaf blade. Finally, the leaves decayed and the plants died.

“…The commercial alkylphenol p ‐NP is oestrogenic (Soto et al ., 1991) and interferes with oestrogen binding to its receptor (Danzo, 1997). p ‐NP accumulates in the environment from several commercial sources, such as pesticides (Weinberger & Rea, 1982), cosmetics (Rantuccio et al ., 1984), commercial phosphate antioxidants (Lowenheim & Moran, 1975), and plastics (Junk et al ., 1974). Human exposure may occur through contaminated water, food, and contact with the skin (Nimrod & Benson, 1996; Toppari et al ., 1996).…”

Harmful micro- and macroscopic effects of the environmental xenoestrogen p-nonylphenol (p-NP) on the male rat reproductive system have been previously reported. In our study, biochemical evidence of epididymal involvement was sought by determining epididymal marker values after exposure at levels below (5, 20 and 50 mg kg-1) and above (100, 250 and 400 mg kg-1) the "no observed adverse effect" level (NOAEL: 50 mg kg-1 day-1). Exposure to p-NL below the NOAEL did not affect biochemical marker values. At levels above the NOAEL, biochemical markers of epididymal function were affected by the exposure of adults, and by maternal exposure (gestational and lactational periods followed by oral exposure until sexual maturity). l-carnitine was unchanged at all levels of exposure. Exposure of adult males to levels above the NOAEL resulted in higher alpha-glucosidase, suggesting increased epididymal secretory activity. This could upset the balance between secretory and reabsorptive function, and could alter the biochemical composition of the epididymal luminal fluid surrounding spermatocytes during the maturation process. Maternal exposure at levels above the NOAEL resulted in higher tartrate-resistant acid phosphatase activity in the caput-corpus epididymidis, which could indicate an oestrogen-mimicking effect.
